Applicaaaiea January 7,1904;

lT all whom .it may concer-7c:

Be it known that I, J ESSE RUBLE JONES, a citi'- L Zen of the UnitedStates, residing at Jackson,

-in the county of Hinds and State of Mississippi,

4have invented certain new and useful Improvements in Convertible Flows,Cultivato rs,.and Harrows; and I do declare the following to be a full,clear, and eXact description of the in-,

ventiOn, such as will enable'othersskilled in the art to which itappertains to make and use Y Mylinvention is animproved convertibleimplement adapted for use either as a plow, cultivator, or barrow; and1t cons1sts1n the construction and combination of devices hereinafterdescribed andclaimed.

In the accompanying`drawings,nF1gure 1 is ,a side elevation of aconvertible implementfem- Ibodying my improvements, showing the hanvdleslowered to raise the-front frame and in dotted lines/showing the handlesraised to lower the front frame, to which the tools are attached. Fig. 2isa top' plan view of the same.

-which are adapted to carrytools, such as harrow-teeth, cultivatingpoints or plows, and

other tools for operating in the Soil, as may be required. The rearframe has wooden side beams 1, on theupper and lower sides of which areflat metallic bars 2, which are wider than the said beams, projectingfrom opposite sides thereof, and are vprovided in their said projectingedges with angular notches 3. The' said notches 3 of the respective bars2 are disposed in vertical alinement and extend 'at intervals from endto end of said bars 2.

Onthe inner sides of the beams 1at a suitable distance from the frontends thereof, are

a'pair of'vertically-disposed Shanks 4, which are angular incross-section to ,correspond with the shape of the notches 3 and are ofa size to enable them lto fit in said notches, and the said Shanks areengaged with appropriate notches 3 and are' secured to the sides of theframe B by means of clamps 5, which may be of any suitable construction.Each of the Said Aclamps 5 is here shown as comprising al pair oflessdiameter innermost.

Seial No. 188,072. (No modem of bolts 6,-liaving eyes 7 at their innerends .engagingthe Shanks 4, the latter passing through said eyes, and ayoke-plateS disposed against the inner side of the longitudinal side.,bar of the lb'eam,`provided with openings throi'iglrwhich said-boltseXtend,Said bolts 'having nuts 9 screwed on theiin'which bear againstthe outer side'of said yoke and coact therewith to clamp the shankl 4 inplace. Thereby the said sh anks 4 are rendered readily detachable fromthe frame B and are also adapted to be adjustable longitudinally thereonand also Vto be adjusted vertically, as will be understood. Each oftheSaid Shanks 4 has at its lower end an eye 10, forming a bearing for anaxle-shaft 11. On the ends of the said axle-shaft are secured a pair ofcarryingwheels 12, which are here shown as of frustoconical form and aredisposed with their sides The upper ends of the Shanks 4 are providedwith eyes 13. A rod 14 is extended through the said 'eyes and forms thepivot for the handles 15, which constitute the levers for raising andlowering the front ends of the yfront frame A.

'llieside' members y'of the rear frame' B are connected together byacross-bar 16, a crossbar l7 `disposed at a suitable distance in rear ofthe bar 16, and by a pair of rearwardly-converging angle-bars 18, thelatter constituting the rear end of the rear frame, as shown. Each ofthe cross-bars 16 17 is here shown as comprising a pair of fiat metallicbars 19, disposed.

on the upper and lower sides of the side mema pair ofcrosS-sectionally-angular Shanks 21,`

`which are similar in construction tothe shanks 4, herembeforedescribed, and are provided at their lower ends, which project below the4rear frame, with eyes 22, through which eX- tends a transverse rod 23.The said Shanks 21 are secured to the side members of the rear frame andare adapted to be vertically ad- IOO justed thereon by means of clamps24, which are similar in construction to the clamps hereinbeforedescribed in connection with the Shanks 4. On the upper portions of theShanks 21 are vertically adjustable segmentbars 25, which are providedon their outer rear sides with sleeves 26', which may beformed integraltherewith, the openings through the said sleeves being angular incross-Section and of a size and shape to enable them to receive theShanks 21. Said sleeves are further provided with set-Screws 27, whichby impinging on the said Shanks secure the segment-bars thereto. It willbe understood that the segment-bars are thus rendered detachable fromthe Shanks and that they may be readily adjusted vertically thereon. Thehandles 15 are provided with locking-dogs 28, which by engagement withthe segment-bars 25 secure the said handles at any desired verticalangular adjustment. The front ends of the said handles are provided withupturned arms 29.

Between the plates or bars 1'7 18 of the rear frame B are securedcoupling-bars 30, which are preferably made of wood, the said bars 30being parallel with the Side members of the rear frame and disposed at asuitable distance from the inner sides thereof. On the inner sides ofthe said coupling-bars are bolted a pair of inclined stay-bars 31,having eyes 32 at their lower rear ends through which the rod 22 extendsand having similar eyes 33 at ltheir upper front ends through which therod 14 extends, which rod, as hereinbefore described, forms the pivotfor the handles 15 and connects the upper ends of the Shanks 4 together.

In coincident notches of the bars 17 18 of the rear frame are securedShanks 34, which are similar in construction tothe Shanks 4 and 21,hereinbefore described, and are provided at their lower ends with eyes35. Clamps 36, which are similar to the clamps hereinbefore described,are employed in connection with the notch-bars 17 18 to secure the saidShanks 34 in place and permit of their vertical adjustment. An axle-rod37 has its bearings in the eyes 35 of the Shanks 34, and on the centerof the said rod are a pair of wheels, so disposed as to form adouble-frusto-conicalshapedv opening-wheel 38, the smaller sides beingoutermost.

The front frame A is somewhat similar in construction to the rear frameB. Its Side members 40 converge Jforwardly to a point, as shown, and thebars 41 on the upper and lower sides of its side members are provided intheir project-ing edges with angular notches 42, adapted for thereception of vertically-disposed crosS-sectionally-angular harrowteeth43 or Shanks 44, adapted for the attachment of tools, such as plowS 45or the like, provided with slecves 46, having erosssectionally-angularopenings to lit on the Shanks 44 and set-screws 47 to clamp them on saidShanks.

The said Shanks and also the said harrow-teeth are secured to thenotched bars 41 and in the notches 42 thereof by means of clamps 48,which are similar in construction to the clamps hereinbefore described.The harrow teeth here shown are in pairs or double-eluled, one end ofeach forming a slightly-curved tooth, and the other, which is on alonger curve, being broadened to form a turning share or plow. Theopposite ends of these teeth are reversely curved, and either theirharrowtooth ends or their share or shovel ends may be engaged with thesoil. By appropriatelyv adjusting the teeth when their share or shovelends are disposed for operation they may hey caused to turn the soileither outwardly or inwardly. The teeth may also be adjusted an gularly,laterally, and may be so Set as to cause their engaging points to trailrearwardly instead of extend forwardly, as here shown. In appropriatenotches 42 of the liront frame are secured cross-sectionally-angularbars Ait) by means of clamps 50, which are similar in construction tothe clamps hereinbelore de,- scribed. Said bars 49 have eyes 50 at theirupper ends, connected by across bar or rod 51, which extends throughthem and to which the angularly-disposed arms 2f) of the handle-levers15 are pivotall y connected, as shown. The rear portions of the frontframe A, which carries various tools for operating` in the soil, bear onthe axle-Shaft 11 of the carryingwheels 12, and the frontend ol the saidfront frame being connected to the handle-levers, as hereinbcforedescribed, it follows that ther said front frame may be raised andlowered by means of the handle-levers to regulate the depth of theimplements in the soil or disenengage them therefrom, as may berequired.

It be will understood that the wheels 12 and 38 when employed as hereshown support my improved convertible implement and that when the frontframe is elevated the implement, by the use of the handle-levers, may bereadily turned at the end of a row. 'ithin the Scope of my inventionother means in lieu of the wheels may be employed to support the rearframe. For instance, earth-workingimplements, such as harrow orcultival'or teeth or plows, may be employed for this purpose. Hence I donot desire to limit myself in this particular.

It will be understood that the several tools are detachable, adjustable,and interchangeable, and that 'my improved implement may be used for allthe purposes ol a plow, cultivator, and harrow.

A clevis 52 is shown in Fig. 2 as connected to the front frame by meansoi clamps 53, having hooks 54, and to the said clevis is connected aswingletree 54 by means ol a bolt55.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isd
